Cardiac arrest patients admitted to intensive care unit after cardiopulmonary resuscitation: a retrospective cohort study to find predictors for mortality

Abstract Background In-hospital cardiac arrest is a common situation in hospital settings. Therefore, healthcare providers should understand the reasons that could affect the results of cardiopulmonary resuscitation. We aimed to determine the independent predictors for poor outcomes after the return of spontaneous circulation in in-hospital cardiac arrest patients, and also look for a relationship between patient's background parameters and the status at intensive care unit. Methods We did a retrospective cohort study using cardiac arrest patients admitted to the intensive care unit after successful cardiopulmonary resuscitation between 2011-2015. Patients' data were gathered from hospital database. Estimated probabilities of survival were computed using the Kaplan-Meier method. Cox proportional hazard models were used to determine associated risk factors for mortality. Results In total, 197 cardiac arrest patients were admitted to anesthesia intensive care unit after successful cardiopulmonary resuscitation in a 4-years period. Of 197 patients, 170 (86.3%) died in intensive care unit. Median of survival days was 4 days. Comorbidity (p= 0.01), higher duration of cardiopulmonary resuscitation (p= 0.02), lower Glasgow Coma Score (p= 0.00), abnormal lactate level (p= 0.00), and abnormal mean blood pressure (p= 0.01) were the main predictors for increased mortality in cardiac arrest patients after intensive care unit admission. Conclusion The consequent clinical status of the patients is affected by the physiological state after return of spontaneous circulation. Comorbidity, higher duration of cardiopulmonary resuscitation, lower arrival Glasgow Coma Score, abnormal lactate level, and abnormal mean blood pressure were the main predictors for increased mortality in patients admitted to the intensive care unit after successful cardiopulmonary resuscitation.

Real and illusory perceptions of patients in induced coma / Percepciones reales e ilusorias de pacientes en coma inducido / Percepções reais e ilusórias de pacientes em coma induzido

ABSTRACT Objective: To identify, in the scientific literature, real and illusory perceptions of adult patients in induced coma. Methods: This is an integrative review of 15 primary studies from the Medline, Web of Science, LILACS, CINAHL and SCOPUS databases. Results: The main memories reported after induced coma were thirst, cold, and pain. In some studies, patients reported they were unable to tell whether they were awake or dreaming, whether it was real or unreal. Satisfactory memories were reported by patients related to the care received and the use of bedside journals. Conclusion: Evidence showed a number of studies aiming to identify delirium, but without a focus on analyzing real or illusory perceptions of patients after induced coma. Thus, this integrative review identified scientific evidence of memories related to perceptions of sedated patients in the intensive care unit.

RESUMEN Objetivo: Identificar, a partir de la literatura científica, percepciones reales e ilusorias de pacientes adultos en coma inducido. Método: Revisión integrativa de 15 estudios primarios alojados en las bases de datos Medline, Web of Science, LILACS, CINAHL y SCOPUS. Resultados: Los recuerdos más reportados luego del coma inducido son sed, frío y dolor. Existen estudios en los que los pacientes afirmaron no distinguir si estaban despiertos o soñando, si era real o irreal. Se identificaron relatos de recuerdos satisfactorios relacionados al cuidado recibido y al uso diario de cabecera. Conclusión: Las evidencias mostraron un abanico de estudios cuyo objetivo era identificar el delirium, aunque con menor enfoque en la identificación real o ilusoria del paciente luego del coma inducido. Así, esta revisión integrativa consiguió identificar evidencias científicas acerca de los recuerdos relativos a la percepción del paciente sedado e internado en la Unidad de Terapia Intensiva.

Método: Revisão integrativa de 15 estudos primários localizados nas bases de dados Medline, Web of Science, LILACS, CINAHL e SCOPUS. Resultados: As principais memórias relatadas após o coma induzido são sede, frio e dor. Há estudos em que os pacientes afirmaram não distinguir se estavam acordados ou sonhando, se o que acontecia era real ou irreal. Identificaram-se relatos de memórias satisfatórias relacionadas ao cuidado recebido e ao uso de diários de cabeceira. Conclusão: As evidências mostraram um leque de estudos direcionados a identificar o delirium, porém com menor foco na identificação da percepção real ou ilusória do paciente após coma induzido. Desse modo, esta revisão integrativa proporcionou a identificação de evidências científicas sobre as memórias relativas à percepção do paciente sedado e em estadia na Unidade de Terapia Intensiva.

Coma mixedematoso e trombo de veia cava superior. Relato de caso e revisão da literatura / Myxedema coma and superior vena cava thrombus: case report and literature review

O coma mixedematoso é uma emergência endocrinológica rara e consiste na máxima expressão do hipotireoidismo, com alta mortalidade por suas complicações hemodinâmicas e ventilatórias, podendo ser agravadas por distúrbios da coagulação. Relatamos o caso de uma paciente diagnosticada com coma mixedematoso e trombo de veia cava superior. Buscamos salientar os distúrbios de coagulação frequentes no hipotireoidismo grave, que contribuem para o aumento da mortalidade deste grupo de pacientes. O diagnóstico e o tratamento precoce do coma mixedematoso, aliados à instituição imediata da terapia para o fenômeno trombótico encontrado, permitiram a evolução favorável do quadro. O relato, juntamente da bibliografia pesquisada, orientou o raciocínio sobre a relação dos distúrbios de coagulação, que ocorrem no hipotireoidismo descompensado. Apesar de poucos relatos, estes distúrbios podem ser frequentes e devem ser pesquisados, pois contribuem com o aumento da mortalidade.(AU)

Myxedema coma is a rare endocrinological emergency, consisting of the highest expression of hypothyroidism with high mortality due to hemodynamic and ventilatory complications, which may be aggravated by coagulation disorders. We report the case of a patient diagnosed with myxedema coma and superior vena cava thrombus. We sought to emphasize the frequent coagulation disorders in severe hypothyroidism, which contribute to increased mortality in this group of patients. The diagnosis and early treatment of myxedema coma, together with the immediate institution of therapy for the thrombotic phenomenon found, allowed the favorable evolution of the condition. The report, together with the literature, has guided the rationale for the influence of coagulation disorders that occur in decompensated hypothyroidism. Despite the few number of reports, these disorders can be frequent and should be investigated because they contribute to the increase in mortality.(AU)

Therapeutic Hypothermia Following Emergent Coronary Artery Bypass Grafting After Failed Percutaneous Coronary Intervention in a Comatose Post-Cardiac Arrest Patient

We report the case of 60-yr-old female in which therapeutic hypothermia (TH) was successfully induced maintaining the target temperature of 34degrees C for 12 hr despite a risk of hypothermia-induced coagulation abnormalities following an emergent coronary artery bypass grafting (CABG) due to failed percutaneous coronary intervention, who suffered a cardiac arrest. Emergent CABG may be a relative contraindication for TH in post-cardiac arrest patients because hypothermia may increase the risk of infection and bleeding. However, the possibility of an improved neurologic outcome outweighs the risk of bleeding, although major surgery may be a relative contraindication for TH.

Hyperammonemic coma presenting as Hashimoto's encephalopathy.

Hyperammonemia is commonly encountered in active liver disease. Evaluation of patients having hyperammonemia with normal liver function is difficult. We present a case referred to us as undiagnosed hyperammonemic coma with normal liver function, who was subsequently diagnosed to have Hashimoto's encephalopathy. In patients with hyperammonemia without hepatic dysfunction, one must search for the presence of hypothyroidism. Hashimoto's encephalopathy though described to be rare in literature, is often underlooked. In patients with undiagnosed coma, one must look for it as it is easy to diagnose and treat.

Emergency and intensive care management of a comatose patient with intracranial hypertension, current concepts.

Altered mental status is a common occurrence in children with acute critical illness. The causes of non-traumatic coma are diverse ranging from neurological to systemic causes. Early appropriate supportive care is essential to avoid preventable secondary insults and optimize the neurological outcome. Evaluation and stabilization of the patient's airway, breathing and circulation (ABCs) must proceed simultaneously with assessments of the depth of coma and the presence of raised intracranial pressure (ICP). Any rapidly correctable cause of coma must be immediately corrected. Most patients with non-traumatic encephalopathies have raised ICP, although papilledema may be absent and the CT scan may be normal if ICP elevation occurs acutely. The most important early treatment for raised ICP is controlled intubation and ventilation followed by osmotherapy. Early control of seizures, including non-convulsive seizures is important. Urgent imaging is indicated in most cases particularly in the presence of afebrile coma, focal signs or papilledema. Following stabilization, isotonic fluids are administered, aiming for euvolemia and euglycaemia. Ventilation should aim for the lower end of eucapnia to avoid causing cerebral ischemia. Surgical options should be explored and, in refractory intracranial hypertension, barbiturates and mild hypothermia may have a role.

there any relationship of age and sex to the etiology and outcome of medical coma?

As the diseases behave differently in males and females and even in different age groups, particular attention was made to classify and observe the distribution of various causes of coma according to age and sex of the patient in order to formulate our indigenous database for future reference. We studied the coma etiology with particular reference to the age and sex of the patient, and the outcome. All the 517 [312 male [60.35%] and 205 female [39.65%]] patients were divided into 7 groups according to decades from age 12 to 80 years. Patients older than 40 years predominated [318 [61.5%]]. Metabolic coma was predominant cause in almost all age groups. Structural coma was increasing progressively with the age. Poisonings were the common cause in patients under 30, representing 35.85% of all comas in the age group 12-20, and 33.70% in the group from 21-30 years. In the next two decades [31-50 years], hepatic and renal failure predominated making up more than half of all causes. Leading causes among males we re poisonings [69 cases], hemorrhagic CVA [48 cases], ischemic CVA [24 cases], renal failure [28 cases] and hepatic coma [35 cases]. Similarly among females causal distribution revealed renal failure [34 cases], followed by hepatic coma [29 cases], and hemorrhagic CVA [26 cases]. Out of the 476 [92%] patients whose outcome could be determined 297 [57.4%] were discharged after recovery and 179 [34.6%] died. Eighty out of 205 female patients died [39%], while 99 out of 312 males had a fatal outcome [31.7%]. We conclude that coma etiology has a significant effect on prognosis, while such significance could not be assigned to age or sex

"Pseudocoma": abulia e oftalmoplegia por hematoma mesencefalico espontaneo / \"Pseudocoma\": abulia and ophthalmoplegia due to spontaneous mesencephalic hematoma

O presente artigo reporta o caso de um senhor que desenvolveu ptose dupla e acinesia como expressäo de hematoma mesencefalo espontâneo. Julgado em coma até a segunda semama de internaçäo, demonstrou-se, inesperadamente, que podia cumprir comandos verbais, sentar, ficar de pé e dar alguns passos com pouca ajuda. Esse caso enfatiza a necessidade de se investigar a real capacidade de comunicaçäo de indivíduos em coma por avenidas de expressäo menos convencionais, uma vez que combinaçöes caprichosas de paralisia e acinesia podem ser erroneamente interpretados como irresponsabilidade patológica. Sugerimos a designaçäo "pseudocoma" para os casos em que a vigília se encontra preservada, porém bloqueada em sua expressäo por lesäo externa dos sistemas motores

Meeting the challenges of coma consequences: development of an instructional nursing intervention plan for comatose patients

The purpose of this study was to detect the direct cause which lead to complications in comatose patients as well as to construct an instructional nursing intervention plan in order to prevent complications following coma. The results indicated that the highest effect which is most leading to coma complications is the long period of hospital stay [multiple r = 0.3829] followed by old age [multiple r = 0.0906, X = 57.9 + 17.3] and nurses performance [multiple r = 0.0640, 81% were scored as unsatisfactory, 14% need more practice and 5% satisfactory]. The study concluded that there is a positive statistical significant correlation between complication and hospital stay and patients' age. While nurses performance was negatively correlated with the prevalence of complications and low nurse-patient ratio

Early mental and neurological sequelae after Japanese B encephalitis.

Japanese B encephalitis is a disease with high mortality and many of those surviving suffer from serious sequelae. During the 1992 epidemic in northern Vietnam 50 patients treated at the Institute for Protection of Children's Health in Hanoi were studied concerning the type of sequelae and the development of the symptoms during the first two months of the disease. The age span was 1 to 15 years. 29 of the patients (58%) did not recover fully during the observation period. Fifteen (30%) showed signs of both neurological and mental disturbances. Nine (18%) only had mental symptoms while 5 (20%) suffered from isolated neurological sequelae. EEG was pathological in 9 out of 30 tested cases (30%); 9 of 23 patients (39%) performed subnormal IQ tests. Deep coma, bronchopneumonia with cyanosis, apnea attacks, prolonged fever and coma were all correlated (without statistical significance) to a higher risk for subsequent sequelae.

Diagnóstico tardío de argininemia en un niño en estado de coma / Late diagnosis of argininemia in a boy with coma

Se presenta el caso clínico de un niño de once años de edad, valorado en una Unidad de Cuidados Intensivos Pedíatricos, en estado de coma, con signos de hipertensión intracraneana, con historia de deterioro neurológico progresivo, espasticidad, convulsiones y diferentes diagnósticos previos. Se detectó hiperamonemia (360 mcg/dL), elevación de arginina en plasma y de ácido orótico en orina, sin acidosis. Se concluyó clínica y bioquímicamente el diagnóstico de argininemia; fue tratado con restricción de proteínas y benzoato de sodio, con lo que se normalizaron los valores de arginina en plasma. Por lo tardío del diagnóstico las funciones neurológicas, el electroencefalograma y los potenciales evocados mostraron solo mejoría parcial. Este es el primer caso publicado en américa Latina. Argininemia
